External Email - Use Caution Dear Support Team,
I'm reaching out for assistance with merging two .mgh files. As I try to generate a surface mapping for all subjects, I merged all volume files (.nii.gz) by mrcalc. So I get a volume file whose voxel value represents the number of valid subjects. And then I convert it to .mgh using mri_vol2surf. But the value of each voxel seems to be thrown out. Because I found the max value of .mgh is not the same as .nii file. I guess I should merge files of all subject in mgh format to maintain the number of valid subjects, but it seems to be a volume encoded surface file format. So I don't know how to merge them. I'm working on Ubuntu18. I would be very grateful for your assistance. Best, Rosie
